the processor will come with everything that you will need.
drop the sound card, 2nd bay drive, and get a cheaper case like a Cooler Master centurion
(thats what i would recommend has 2 120s in it and really nice cooling)
and see if you can upgrade to a gigabyte DS3 or just S3
that PSU is crap get somehting form a respectible brand like Antec, Hiper, FPS etc.
also if you have to get 1 gig o ram try to get 1gb stick instead of 2 by 512
